Abstract

This report summarises extensive X-ray diffraction residual stress measurements conducted on three different materials, shot-peened spring steel, heat-treated aluminium and a sample of ground titanium. The purpose of the study was to investigate the repeatability of the XRD measurement method and relative sensitivity of the measurement technique to changes in the test set-up, including the height offset of the specimen, the counting time and the number of Psi tilts used.
